A catch can does not, in any way, stop oil pressure, interfere with lubrication of vital components such as bearings or galleys, have a single thing to do with the oil pump, pick-up tube or seal. It seems to me that this guy should escalate with GM and bash this dealer into oblivion - if his story is true.
If you're scared of the catch can voiding a warranty, which it won't, take it off before service. Easy solution.
